SPRINGWORK.

No. 81 1,234 Specification of Letters Patent. Patented Jan. 30, 1906.

Application filed August 4, 1905. Serial No. 272,640.

To all whom it mm/y concern.-

Be it known that I, Rev C. MANsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Imrovements in Springworks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to springwork for couches, chairs, and the like usually provided with spring-cushions, and has particular reference to the means for connecting the tops of the springs.

The invention consists of the construction and details hereinafter particularly described and then pointed out in the appended claims.

In the drawings, Figure 1 is a plan view of a section of springwork, illustrating one embodiment of the invention. Fig. 2 is a detail perspective view, on an enlarged scale, showing a modification of the connection between the springs. Fig. 3 is a detail side view of a further modification of the invention, and Fig. 4 illustrates a further modification in which a link is employed to connect the springs.

Referring to the drawings, the numeral 10 indicates a series of springs forming a portion of a springwork construction. These springs are usually arranged in banks or rows, as shown, and may be of any suitable character, such as the ordinary coil or spiral spring, although in the present instance the springs are shown as formed with the top coil or portion 11 rectangular. The springs may be mounted on the support or frame in any suitable manner. The present invention relates to improved means for connecting the tops of the springs without the employment of tierods or clips such as are generally used. In the construction shown in Figs. 1 and 2 a hook-and-loop connection is provided for connecting the springs. For example, the top coil 1 1 of each spring is provided at opposite points with hooks 12, while at points of the top coil ninety degrees removed from the hooks 12 the coils are formed with loops 13, with which the hooks of adjacent springs are designed to cooperate. The hooks 12, which may extend upwardly or downwardly, as desired, may be formed by bringing a portion of the wire of the topcoil 11 together at a suitable point and then. bending such portion into hook shape, as shown. The loops 13 may be provided by the angles formed by the sides of the rectangular top coil, as shown in Fig. l, or, as shown in Fig. 2, the angles may be bent into the shape of eyes 1 1, which may be more or less open, as desired.

In setting up the springs illustrated in the present instance the tops 11 are so disposed that the hooks 12 of each spring are in a line at a right angle to the hooks of the adjacent springs, so that each hook is opposed to a loop or eye of an adjacent spring, and the hooks engaged with the loops to connect the springs together, as shown in Fig. 1. The points of connection between adjacent rows of springs are disalined, being offset in alternation at opposite sides of a median line passin between the rows of springs.

TVhere the hooks are bent upwardly, as shown in the drawings, they may be provided with depressed seats 15, whichreceive the loops or eyes of the adjacent springs, thereby bringing the tops of the coils in the same plane and presenting a flatter surface than would otherwise eXist.

Instead of connecting the springs directly together a connecting-link 16 may be employed and provided at its ends with eyes 17, the adjacent portions of the top coils of the springs being provided with hooks engaging the eyes, as shown in Fig. 4.

The connections shown, while they tie or connect the springs together, so as to avoid any wabbling or lateral movement of the springs with relation to each other, permit of independent movement of the springs in the manner necessary to provide the desired flexibility of the spring-top, the connections providing, when the springs are connected to the usual border or edge wire a continuous connected surface. In order to prevent the loops or eyes becoming disengaged, the ends of the hooks may be bent so as to more or less close the mouth of the hook, as shown in Fig. 3.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a device of the class described, a coilspring having a rectangular top, an opposite pair of the angles of which are bent into hook form to engage the tops of adjacent springs at points between the hooks of the latter.

ICC

2. Ina device of the class described, springarranged in longitudinal and transverse banks or rows and having rectangular tops, one pair of the opposite angles of each top be- 5 ing provided with hooks and the other pair With eyes, and each hook engaging an eye of an adjacent spring, the points of connection between adjacent rows of springs being offset in alternation at opposite sides of a line median of such rows. 10 In testimony whereof I affiX my signature in presence of two witnesses.

ARTHUR B. SEIBOLD, ELIZABETH MOLITOR It is hereby certified that in Letters Patent No. 811,234, granted January 30, 1906,

upon the application of Ray C. Manson, of Chicago, Illinois, the title of the invention should read Springwork instead of Springworks; on page 1, line 6, for the Word Springworks read Springwork, and page 2, lines 1-2, for the compound word spring- 7 arranged read springs arranged; and that the said Letters Patent should be read With these corrections therein that the same may conform to the record of the case in the Patent Office.

Signed and sealed this 20th day of February, A. D., 1906.
